ATTACHMENT F03 SPOOLER S.

Specification of Letters Patent.

part of this specification, in explaining its change of gear for varying the length of the traverse as occasion may require.

The principal ob ect of my invention is to provide as simple an expedient as possible.

and one which will permit of an easy and accurate se ting of the traverse rail.

The invention can best be seen and under stood by reference to the drawings in which only those parts of the spooler are-shown necessary for a proper understanding of the invention and in which Figure 1 shows such parts andcombined attachment in side elevation.

bracket 3. In practice a series of the rods 2 and connecting brackets 3 are employed for supporting the traverse rail, only one being shown in the present instance.

The traverse rail is moved up and down by the reciprocation of the lifting rod 2,

which effect is obtained through a forward and reverse movement imparted to a shaft 1. This shaft runs along the side of the spooler and is supported to turn in bearings (not shown). The motion of the shaft 1- is imparted to the lifting rod 2 for recipro- United States, have invented a new and use-.

eating it and the traverse rail as the shaft 4 is reversely turned, by a pinion 5 fixed to the shaft iand in operative engagement with the toothed edge or rack 6 on the side of the lifting rod.

Areversing movement is imparted to the shaft 4 by a gear 7 operated by a driving mechanism (not shown) well known to those skilled in the art.

Arranged upon the end of the shaft l to embrace the same is a sleeve 8 which is keyed to the shaft and by which the shaft is diametrically widened. provided with a relatively long hub 9. which turns upon the sleeve 8. The sleeve keyed to the shaft has secured to the outer end thereof, and preferably by integral conneetion, a clamping plate 10 having in it a curved slot 11. The arrangement of the parts is such that the plate 10 frictionally bears against the outer side 12 of the gear.

The gear is also preferably made dished to receive the plate so that the outer side of the plate is practically flush withwthe ex treme outer edge of the rim of the gear. The plate is coupled or bound to the ear by means of a binding screw 18 the head of which and interposed washer 14: bear against the outer side of the plate adjacent the slot therein while the shank of the screw passes through the slot and fastens into the body of the gear. Jpon loosening the screw and assuming the gear 7 to be held in a fixed position, the shaft may be turned in an opposite direction to any adjusted position within the limits defined by the slot 11.

In order that the shaft may be easily turned with relation to the gear uponthe loosening of the binding screw as aforesaid, the shaft is provided with a squared outer end or head 15 by which a wrench may be applied to the shaft for turning it.

In the operation of the device the proper adjusted position of the traverse rail is obtained by loosening the binding screw 13 and then turning the shaft at with relation to the gear 7 held fixed until the traverse rail is properly set with relation to the spool. The binding screw is then again tightened thus completing the operation.

hen the binding screw 13 is loosened the normal tendency of the parts will be for the traverse rail and parts immediately connecting therewith to fall or otherwise assume a displaced position as when the traverse rail T The gear 7 is Sol is overweighted. Such tendency, however, is prevented by theclamping plate 10 acting as a brake. It will be observed that the plate has a relatively large frictional bearing surface against the gear so that when the binding screw is loosened the frictional sur face between the plate and gear will be sufiicient to prevent displacement of the traverse rail, yet permitting of the shaft 4: being turned when power is applied to the head of the shaft by a wrench or otherwise. By this means an absolute nicety of adjustment can be easily obtained and without danger of possible displacement of the traverse rail. Attention is also directed to the fact that the binding screw lies immediately adjacent the head of the shaft so that an operator has both of these parts immediately at hand, which also furthers facility of adjustment.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 2- 1. In a machine of the type specified, a traverse rail, mechanism assisting in actuating said rail to have movement in reverse directions, said mechanism comprising in part a shaft, a gear arranged to turn independently of the shaft, and means for coupling the gear to the shaft whereby it may be turned thereby, said means comprising a member rotatable with the shaft and an attaching device for securing said member to the gear, said member cooperating with the gear in a manner whereby upon the loosening of said device with the gear held fixed against rotation, said member and gear may be held to bear frictionally against one another and prevent accidental turning of said shaft and consequent displacement of said traverse rail but will permit the turning of said shaft and consequent positioning of the traverse rail upon the application of power to the shaft for turning it.

2. In a machine of the type specified, a traverse rail, mechanism assisting in actuating said rail to have movement in reverse directions, said mechanism comprising in part a shaft, a gear arranged to turn independently of said shaft, and means for coupling the gear to the shaft, said means co1nprising a member rotatable with the shaft and a binding screw for securing said member to the gear, said member cooperating with the gear in a manner whereby upon the loosening of said binding screw and with the gear held fixed against rotation, said member and gear may be held by the screw to bear frictionally against one another and prevent accidental turning of said shaft and consequent displacement of said traverse rail but will permit the turning of said shaft and consequent positioning of the traverse rail upon the application of power to the shaft for turning it.

3. In a machine of the type specified, a traverse rail, mechanism assisting in actuating said rail to have movement in reverse directions, said mechanism comprising in part a shaft, a gear, a slotted plate rotatable with said shaft, said plate having a hub embracing said shaft and upon which said gear is arranged to turn independently of said shaft, and a screw passing through said slotted plate and fastening into-said gear for binding together said gear and plate, said plate cooperating with said gear in a manner whereby upon the loosening of said screw and with said gear held fixed, said plate and gear may be held by the screw to bear frictionally against one another and prevent accidental turning of said shaft and consequent displacement of said traverse rail but will permit the turning of said shaft and consequent positioning of the traverse rail upon the application of power to the shaft for turning it.
